Hydrodynamic radius of polymer

Webthat polymers in good solvents are shaped like expanded coils. Thus, the radius calculated from DLS corresponds to the apparent size of the dissolved particle, or the … Web14 apr. 2024 · The interaction of the polymer chains with the flow is caused by the hydrodynamic drag that the fluid exerts on the beads. Network theories, on the other hand, view the polymer as a network of springs connected at junction points. The interaction between the polymer and the flow arises from the motion of these junctions.
